There are three types of polishing machines, straight machine, eccentric machine, forced eccentric machine
What is a straight machine? Referred to as the RO machine, it is also called the spin-casting machine, but everyone calls it differently.
This machine is a polishing machine that only rotates in one direction, rotating clockwise. And the function of this machine: It can remove deep scratches, that is to say, it can remove 600 mesh to 800 mesh sandpaper prints, and it can also remove 1500 mesh to 2000 mesh sandpaper prints. It is a necessary polishing equipment for every automobile art technician.
Advantages of straight machine: high efficiency and very fast removal of scratches.
Disadvantages of straight machine: low safety, fast temperature rise, glare after polishing.
During the construction process, especially the edges and corners, it is easy to be thrown through if you are careless. Even if your polishing technique is very good, there will be more or less glare. If your technique is not good, more glare will be produced after polishing, which will turn the car into a "rainbow car"!
What is an eccentric machine? Referred to as DA machine, some people call it eccentric machine or vibration throwing machine, which is called differently.
This machine rotates randomly, and the trajectory is an irregular ellipse. The machine is divided into 15mm and 21mm, and there are other models, but these two models are the most popular models on the market.
In addition to the difference between the backplane and the eccentric block of 15mm and 21mm, both domestic and foreign countries have serious selection difficulties. Comprehensive tests have basically confirmed that the cutting capabilities of the two polishing machines are basically the same.
The advantages of the eccentric machine: high safety, no glare after polishing, and the surface temperature of the car paint after polishing is warm, and it will not be as hot as the car paint surface after polishing with a straight machine. Whether you are a novice or a technician for many years, Choosing an eccentric machine is your must-have polishing artifact! And the mirror effect is better than the RO machine.
Disadvantages of eccentric machine: low efficiency, the eccentric machine cannot be removed for deep scratches.
What is a forced eccentric machine? Referred to as GA machine, no other names have been found yet.
Because the popularity of this machine in the market is extremely low, this machine is based on the eccentric machine, adding a gear drive system, so that the eccentric machine is forced to rotate like a straight machine, and the cutting force of the forced eccentric machine is between the eccentric machine and the straight machine. In the middle, the temperature is lower than the straight machine, higher than the eccentric machine, and in terms of efficiency, it is slightly slower than the straight machine, slightly faster than the eccentric machine, safety is higher than the straight machine, and lower than the eccentric machine.
